PLOW.

SPECIFICATION forming part of Letters Patent No. 233,827, dated October 26, 1880,

Application filed May 4, 1880.

To all whom it may concern:

Be it known that I, DAVID WOLF, of Avon, in the county of Lebanon and State of Pennsylvania, have invented certain new and useful Improvements in Flows; and I do hereby declare the following to be a full, clear, and exact description of theinvention,such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

The object of my invention is to provide certain improvements in plows which will render the latter economical in manufacture, efficient in operation, and durable in service.

With these several ends in view the invention consists of the parts and combination of parts hereinafter described and claimed.

Referring to the drawings, Figure l is a View of the mold-board side of aplow embodying my improvements. Fig. 2 is a view of the land side of the plow. Fig. 3 represents the mold-board side of the plow with the share and cutter removed. Fig. 4 represents the land side of the plow with the cutter removed. Fig. 5 represents, in detail views, the cutter and share. Fig. 6 is a detail view, in vertical transverse section, through the cutter and its angular fastening device. Fig. 7 is'a longitudinal sectional view, showing the plow-point in side elevation. Fig. 8 is a detail view, in vertical transverse section through the fastening device which secures the rear extremity of the plow-point to the landside. Fig. 9 is a detail view of the clamp which secures the plow-beam in lateral adjustment on the plow-handle.

The mold-board A has standard B,formed in single piece therewith, the mold-board being provided with vertical groove a in line with offset 1), which latter extends along the forward portion of the standard. A flat-sided bolt, 0, fits in this mold-board groove and seats against this standardbflset. It passes through the plow-beam D and the plow-point E, and binds different parts of the plow together, as will immediately appear.

The cutter F has its upper portion provided with a lateral lug, c, which fits in a recess, (1, formed in the forward edge of the mold-board. This lug embraces that portion of bolt 0 which (No model.)

is located between the mold-board groove and the standard-offset. The lower portion of the cutter is provided with a hole, 6, in which fits the outer extremity of the angular fastening device G. The lower arm of the latter fits in the horizontal branch of opening f, formed in the mold-board, and its upper arm fits in the vertical branch of said opening. The bolt 0 serves to clamp this angular fastening device in position by the same force which maintains the plow-point in place.

The share H is made substantially of triangular form, its rear portion, g, being depressed below its working portion h, and fitting beneath the mold-board. Said working portion of the share is fitted between the plow-point and a forward lug, Z, formed on the outer side of the mold-board. A lug, m, formed thereon, fits in a slot, n, with which the plow-point is provided. A belt or rivet, L, passes through the mold-board, and also through the depressed portion of the share. Preferably I make the parts of such relative construction that the share is wedged in position. The plow-point is adapted to have both its ends used as working points, and also to have both its upper and under sides used as the ground side. This self-sharpening plow-point has two slots, a, formed on each of its sides, to respectively receive the lug m of the share, as the plow-point is thus changed with either end front and either side up. The point, as thus far described, is similar to the one patented by me May 14, 1878, the improvement in its construction being as follows: The plow-point is made with its vertical sides in continuous line throughout their entire length, and the horizontal transverse section of the plow-point is as great at the central portion of its length as it is at its extremities. The width of the plow-point bein g thus maintained at the very portion thereof which receives the strain, the plow-point is enabled to withstand the work better than if it were decreased in width at said central portion.

The upper landsidebar, n, is provided with a lateral stud on its inner side, throughwhich passes a screw, 19. A nut, 19 is threaded on the projecting extremity of this screw, and clamps the rear extremity of the plow-point to the under side of said lug.

A loop, P, embraces one of the plow-han dles, R, and the eye of an eyebolt, S, engages with its upper cross bar. This eyebolt passes through the plow-beam and is laterally adjustable on the loop. The latter obviates the passage of bolts through the plow-handle, and thereby prevents it from being weakened at this point, at the same time permitting full adjustment of the plow-beam, so as to take more or less land.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a plow, the combination, with a moldboard having a vertical groove, and a standard having a front offset formed above and disconnected from the groove, of a flat-sided bolt whose lower portion fits in said groove, and whose upper portion bears laterally against said offset, the central portion of the bolt being located in the space formed between the groove and offset, substantially as set forth.

2. In a plow, the combination, with a moldboard provided with a vertical groove, and a' standard provided with a front offset, of a flatsided bolt which fits in said groove and seats against said offset, and a cutter provided with fits on the forward cross-bar of the loop, said bolt passing up through the plow-beam and adapted to laterally adjust the latter by sliding its eye on said loop-bar, substantially as set forth. w

4. In a plow, the combination, with the double plow-point having its vertical sides formed straight throughout their entire length, and the lateral stud formed on the landsidebar, of the bolt which passes through the stud, and is provided with a nut whose lower portion depends below the stud and has lateral bearing against the plow-point, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 26th day of April, 1880.
